Procryptocerus convexus

Quick Summary

• Difficulty: Unknown, Insufficient data for difficulty rating
• Origin & Habitat: Lowland rainforest in Brazil (Amazonas, Pará) and Colombia (Caquetá) at around 260 m elevation ^[4][2]
• Colony Type: Unknown, colony structure has not been documented
• Size & Growth:
  • Queen: Size data unavailable, no queen measurements exist
  • Worker: Less than 4 mm total length ^[1]
  • Colony: Unknown, no colony size data exists
  • Growth: Unknown
  • Development: Unknown, no development data exists (Development timeline unstudied. Based on related Attini species, estimates suggest 6-10 weeks at optimal temperature, but this is inferred.)
• Antkeeping:
  • Temperature: Likely 22-26°C based on lowland Neotropical distribution, start in this range and observe^[2]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on rainforest habitat^[2]
  • Diapause: Unknown, no data on overwintering requirements
  • Nesting: Natural nesting habits unknown. Likely nests in rotting wood or leaf litter. Use small Y-tong, plaster, or soil nests with moisture retention
• Behavior: Behavior is unstudied. Based on Attini tribe, likely forages for fungal substrates. Escape risk is high due to small size (under 4 mm). Temperament unknown, exercise caution.
• Common Issues: completely unknown biology, no documented care information, making success uncertain, no development data, egg-to-worker timeline unknown, so normal development is unclear, colony structure unconfirmed, queen number requirements unknown, escape risk, tiny size means they can escape through standard barriers, no confirmed diet, specific food preferences unknown, may require specialized diet

Species Identification and Distinction

Procryptocerus convexus workers have a convex dorsal profile and lack mesonotal processes ^[1]. The frons has a clathrate sculpture, and the first gastral tergite is smooth and shiny with sparse erect hairs ^[2][3]. Brazilian populations have shorter stiff pilosity than Andean relatives ^[3]. This species was elevated to full species status in 2002 based on morphological examination ^[4].

Distribution and Habitat

Procryptocerus convexus is known from Brazil (Amazonas, Pará) and Colombia (Caquetá) ^[4][2]. The type locality is in Pará, and specimens have been collected from Ilha de Curari ^[4]. A worker was found in Caquetá at 260 m elevation, indicating lowland tropical forest habitat ^[2].

Why This Species is Challenging to Keep

The scientific literature states that nothing is known about the biology of this species ^[5]. This includes no information on founding behavior, colony structure, diet, nesting, or development. Keeping this ant requires experimental conditions with high risk of failure due to unknown requirements.

Experimental Care Approach

Care must be based on inference from habitat and related species. As an Attini member, it may require fungal substrates, but this is speculative. Use small-scale nests like test tubes with fine mesh, Y-tong, or plaster nests. Temperature should be 22-26°C based on lowland distribution ^[4][2]. Humidity should be moderate to high, with a moist nest substrate. Start with standard ant foods and observe acceptance.

Legal and Ethical Considerations

Verify legal status before acquiring this species, as it is native to Brazil and Colombia. Ensure colonies are from permitted breeders. Given the lack of data, colony failure is likely. If kept, document observations to contribute to antkeeping knowledge.
